ELECTRICAL TERMINAL.

Application led November 13, Y1924. Serial No. 749,640.

My invention relates to electrical terminals, and more particularly to terminals especially suitable for employment in connection with rail bonds, although they may be used in other relations.

One object of my invention is to provide an improved manner of forming conductor terminals and of attaching them to the conductors with which they are associated.

Another object of my invention is to simplify and improve generally the methods of making and the lgeneral arrangement of devices of the character referred to.

One form which my invention may take is shown in the accompanying drawing wherein Fig. 1 is a perspective view showing a structure embodying my invention; Fig. 2 is a view, on an enlarged scale, of a portion of the bond of Fig. 1; Fig. 3 is an elevational view of the device of Fig. 1; Fig. 4 is a sectional view of the terminal of Fig. 1; F ig. 5 is a sectional view, on an enlarged scale, of a portion of the device of Fig. 1; F ig, 6 is a view showing one step in the formation of the terminal members, and 7 is a view showing still another step.

The article is shown as applied to railroad rail sections 8 having splice bars 9 and comprises a conductor 10, preferably of copper, secured at its ends to terminals 11 which are held in position upon the rails by clips 12, as'described more fully in my copending application, Serial No. 749,641 filed November 13, 1924. l

In order to form the terminals 11 I preferably shear a plurality of blanks from a plate of mild steel or the like, in the manner shown in Fig. 6, and then bend said blanks to the form shown in Fig. 7. Thereafter the end of the cable 10 is placed with the deeper portion of the semi-cylindrical member 11 as shown in Fig. 4. A short metal platella is then placed between the sides of the mem bei' 1l at their deeper portions, as .shown more clearly in Fig. 5. A welding heat is then applied to the end of the copper conductor 10 to cause a fusing of the copper to and filling of the space between the lside walls of the sleevelike member 11, or metal may be deposited therein by electric welding, until the fused metal is substantially flush with the longitudinal edges of the member 11, the plate 11a being simultaneously fused into place. The plate 11a serves as a strengthening member and also gives a finished effect.

It will be noted that Vthe longitudinal edges o'f the member 11a are flared slightly as shown more clearly in Figs. 2 and 5, so that inclined effect produced by the form of the j terminals 11 directs the cable ends upwardly in such manner that the conductor 10 may be disposed across the base of the splice bar, which is a higher plane, with a minimum of distortion adjacent to the points of juncture between the conductor 10 and the terminals 11.

Various changes in detail and general arrangement may be made without departing from the spirit and scope of the invention as delined in the accompanying claims.

I claim as my invention:

1. A conductor terminal comprising a loni gitudinally recessed member of decreasing depth toward one end thereof and adapted to contain one end of a conductor of smaller diameter than the depthof the deeper portion of the recess, a plate disposed across the conductor and between the walls of the recess at said deeper portion, and means for securing said plate and conductor in position in said recess.

2. A conductor terminal comprising a longitudinally recessed member of decreasing depth toward one end thereof and adapted to contain one end of a. conductor of smaller diameter' than the depth of the deeper' portionV of the recess, a plate disposed across the conductor and between the walls kof the recess at said deeper portion, and means for securing said plate and conductor in posi-` tion in said recess, the said plate being disposed entirely between adjacent Walls of said recess.

In testimony whereof I the said EDUARD vSCHENK have hereunto set my hand.
